Abstract
Due to the ambiguity related to the lack of phase information, determining the physical parameters of multilayer thin films from measured neutron and X-ray reflectivity curves is, on a fundamental level, an underdetermined inverse problem. This ambiguity poses limitations on standard neural networks, constraining the range and number of considered parameters in previous machine learning solutions. To overcome this challenge, a novel training procedure has been designed which incorporates dynamic prior boundaries for each physical parameter as additional inputs to the neural network. In this manner, the neural network can be trained simultaneously on all well-posed subintervals of a larger parameter space in which the inverse problem is underdetermined. During inference, users can flexibly input their own prior knowledge about the physical system to constrain the neural network prediction to distinct target subintervals in the parameter space. The effectiveness of the method is demonstrated in various scenarios, including multilayer structures with a box model parameterization and a physics-inspired special parameterization of the scattering length density profile for a multilayer structure. In contrast to previous methods, this approach scales favourably when increasing the complexity of the inverse problem, working properly even for a five-layer multilayer model and a periodic multilayer model with up to 17 open parameters.

Abstract
BACKGROUND The family of perfluoroalkyl and polyfluoroalkyl substances (PFAS) raised concern for their proven bioaccumulation and persistence in the environment and animals as well as for their hazardous health effects. As a result, new congeners of PFAS have rapidly replaced the so-called "old long-chain PFAS" (mainly PFOA and PFOS), currently out-of-law and banned by most countries. These compounds derive from the original structure of "old long-chain PFAS", by cutting or making little conformational changes to their structure, thus obtaining new molecules with similar industrial applications. The new congeners were designed to obtain "safer" compounds. Indeed, old-long-chain PFAS were reported to exert thyroid disruptive effects in vitro, and in vivo in animals and humans. However, shreds of evidence accumulated so far indicate that the "restyling" of the old PFAS leads to the production of compounds, not only functionally similar to the previous ones but also potentially not free of adverse health effects and bioaccumulation. Studies aimed at characterizing the effects of new-PFAS congeners on thyroid function indicate that some of these new-PFAS congeners showed similar effects. PURPOSE The present review is aimed at providing an overview of recent data regarding the effects of novel PFAS alternatives on thyroid function. RESULTS AND CONCLUSIONS An extensive review of current legislation and of the shreds of evidence obtained from in vitro and in vivo studies evaluating the effects of the exposure to novel PFOA and PFOS alternatives, as well as of PFAS mixture on thyroid function will be provided.

Abstract
Abstract Radiomics represents the convergence of artificial intelligence and radiological data analysis, primarily applied in the diagnosis and treatment of cancer. In the head and neck region, squamous cell carcinoma is the most prevalent type of tumor. Recent radiomics research has revealed that specific bio-imaging characteristics correlate with various molecular features of Head and Neck Squamous Cell Carcinoma (HNSCC), particularly Human Papillomavirus (HPV). These tumors typically present a unique phenotype, often affecting younger patients, and show a favorable response to radiation therapy. This study provides a systematic review of the literature, summarizing the application of radiomics in the head and neck region. It offers a comprehensive analysis of radiomics-based studies on HNSCC, evaluating its potential for tumor evaluation, risk stratification, and outcome prediction in head and neck cancer treatment.

Abstract
This work provides a comprehensive illustration of a crystalline melt memory effect recorded for three solvates of the 2,7-bis(2-(2-methoxyethoxy)ethoxy)benzo[b]benzo[4,5] thieno[2,3-d]thiophene (OEG-BTBT) molecule with dichloromethane (DCM) molecules. Combined optical microscopy and X-ray diffraction measurements at different temperatures are used to get an overview of the structural and morphological properties like melting points, isotropic transition temperatures, induction times, and crystallization kinetics of the three forms. An outstanding observation is made upon annealing the three polymorphs at temperatures well above their respective melting points as well as above the optical clearance temperature. After cooling back to room temperature, recrystallization results in the formation of the initial phase present before the annealing process. This melt memory effect is observed for all three solvates. These observations can be correlated to the strong interaction between the DCM molecules and the oligoethylene glycol side chains, even in the molten state. This conclusion rationalizes the experimental observation made upon solvent vapor annealing of the crystalline sample with DCM, which unambiguously transformed the system into a disordered state.

Abstract
Objectives Dysphagia affects 16% of patients undergoing total laryngectomy; of these, a third is due to pharyngoesophageal stenosis. Currently, the treatment is cyclic dilation of the stricture and Montgomery Salivary Bypass Tube (MSBT) application. The aim of this study is to assess whether using Self-Expandable Metal Stent (SEMS) may give better results after a non-durable response to repeated dilatation and application of MSBT. Materials and Methods We verified whether using SEMS after at least 3 cyclic dilations and application of MSBT results in a longer dysphagia-free time in laryngectomized patients with pharyngolesopha-geal stenosis. Secondary outcomes were the duration of the procedures, radiation exposure and complications. Results We enrolled 6 patients with a median age of 65 years (QR 62.5 - 75.75), of which 50% had undergone radiotherapy. Friedman's test for the duration of the dysphagia-free period did not show a statistically significant difference between the two groups (Friedman chi-squared = 2.6667, df = 1, p-value = 0.1025). The time required to implant the MSBT was significantly less than that required to implant the SEMS (Friedman chi-squared = 6, df = 1, p-value = 0.01431). Radiation exposure was absent for MSBT, while SEMS implant required an exposure to X-rays during the procedure and after 48 hours for placement verification. Two patients experienced short-term complications after SEMS implantation and one after two weeks from MSBT implantation; none of them had any health consequences. Conclusion In patients who are already undergoing cyclic dilations and application of MSBT, switching to SEMS is not beneficial. Furthermore, MSBT has a significantly shorter implant procedure, does not expose the patient to X-rays, and, in the absence of complications, has a longer duration before removal.

Abstract
The discovery of new polymorphs opens up unique applications for molecular materials since their physical properties are predominantly influenced by the crystal structure type. The deposition of molecules at surfaces offers great potential in the variation of the crystallization conditions, thereby allowing access to unknown polymorphs. With our surface crystallization approach, four new phases are found for an oligoethylene glycol-benzothienobenzothiophene molecule, and none of these phases could be identified via classical polymorph screening. The corresponding crystal lattices of three of the new phases were obtained via X-ray diffraction (XRD). Based on the volumetric considerations together with X-ray fluorescence and Raman spectroscopy data, the phases are identified as solvates containing one, two or three solvent molecules per molecule. The strong interaction of dichloromethane with the oligoethylene glycol side chains of the molecules may be responsible for the formation of the solvates. Temperature-dependent XRD reveals the low thermal stability of the new phases, contrary to the thermodynamically stable bulk form. Nevertheless, the four solvates are stable under ambient conditions for at least two years. This work illustrates that defined crystallization at surfaces enables access to multiple solvates of a given material through precise and controlled variations in the crystallization kinetics.

Abstract
Establishing a common language that allows univocal and objective communication in describing wounds and their healing is of utmost importance in defining the diagnostic hypothesis and proper wound management. To measure the level of agreement on the description of wounds, an international study was performed among experts of different professional backgrounds on several common terms used to describe ulcerative lesions. A panel of 27 wound care experts anonymously completed a multiple-choice questionnaire on 100 images of 50 ulcerative lesions. The participants were asked to describe each image using a set of pre-defined terms. An expert data analyst interpreted the questionnaires to map the level of agreement on the used terminology. Our findings show a very low level of agreement among experts in using the proposed terminology to describe the wound bed, the wound edge, and the surrounding skin conditions. Efforts should be planned to find a consensus on the correct use of terminology for wound description. To this aim, partnership, consensus, and agreement with educators in medicine and nursing are necessary.

Abstract
Tumor tissues are constituted by a dynamic diversity of malignant and non-malignant cells, which shape a puzzling biological ecosystem affecting cancer biology and response to treatments. Over the course of the tumoral disease, cancer cells acquire genotypic and phenotypic changes, allowing them to improve cellular fitness and overcome environmental and treatment constraints. This progression is depicted by an evolutionary process in which single cells expand as a result of an interaction between single-cell changes and the local microenvironment. Recent technological developments have made it possible to depict the development of cancer at the single-cell level, offering a novel method for understanding the biology of this complex disease. Here, we review those complex interactions from the perspective of single cells and introduce the concept of omics for single-cell studies. This review emphasizes the evolutionary dynamics that control cancer progression and the capacity of single cells to escape the local environment and colonize distant sites. We are assisting a rapid progression of studies carried out at the single-cell level, and we survey relevant single-cell technologies looking at multi-omics studies. These forefront approaches will address the combined contribution of both genetic and non-genetic factors to cancer progression and will pave the path for precision medicine in cancer.

Abstract
Time-driven activity-based costing (TDABC) is suggested to assess costs within the value-based healthcare approach, but there is a paucity of applications in chronic diseases such as deep vein thrombosis (DVT) and leg ulcers. In this context, we applied TDABC in a cost-effectiveness analysis comparing venous stenting to compression ± anticoagulation (standard of care-SOC) from both hospital and societal perspectives in Italy. TDABC was applied to both treatments to assess costs that were included in a cost-effectiveness model. Clinical inputs were retrieved from the literature and integrated with real-world data. The Incremental Cost Utility Ratio (ICUR) of stenting compared to SOC was EUR 10,270/QALY and EUR 8962/QALY for hospital and societal perspectives, respectively. The mean cost per patient for venous stenting of EUR 5082 was higher than the Diagnosis-Related Group (DRG) reimbursement (EUR 4742). For SOC, an ulcer healing in 3 months costs EUR 1892, of which EUR 302 (16%) is borne by the patient versus a reimbursement of EUR 1132. TDABC showed that venous stenting may be cost-effective compared with SOC but that reimbursement rates may not completely cover the real costs, which are partially sustained by the patients. A more efficient policy for covering the real costs may be beneficial for both clinical centers and patients.

Abstract
In typical aqueous systems, including naturally occurring sweet and salt water and tap water, multiple ion species are co-solvated. At the water-air interface, these ions are known to affect the chemical reactivity, aerosol formation, climate, and water odor. Yet, the composition of ions at the water interface has remained enigmatic. Here, using surface-specific heterodyne-detected sum-frequency generation spectroscopy, we quantify the relative surface activity of two co-solvated ions in solution. We find that more hydrophobic ions are speciated to the interface due to the hydrophilic ions. Quantitative analysis shows that the interfacial hydrophobic ion population increases with decreasing interfacial hydrophilic ion population at the interface. Simulations show that the solvation energy difference between the ions and the intrinsic surface propensity of ions determine the extent of an ion's speciation by other ions. This mechanism provides a unified view of the speciation of monatomic and polyatomic ions at electrolyte solution interfaces.

Abstract
A selective and sensitive liquid chromatography-tandem mass spectrometry method was developed and validated for accurate determination of CHF6550 and its main metabolite in rat plasma and lung homogenate samples. All biological samples were prepared by simple protein precipitation method using deuterated internal standards. The analytes were separated on a HSS T3 analytical column with 3.2 min run time at flow rate of 0.5 mL/min. The detection was performed on a triple-quadrupole tandem mass spectrometer equipped with positive-ion electrospray ionization by selected-reaction monitoring of the transitions at m/z 735.3 → 98.0 for CHF6550 and m/z 638.3 → 319.2 and 638.3 → 376.2 for CHF6671. The calibration curves for plasma samples were linear between 50 and 50000 pg/mL for both analytes. The calibration curves for lung homogenate samples were linear within 0.1-100 ng/mL for CHF6550 and 0.3-300 ng/mL for CHF6671. The method was successfully applied to a 4-week toxicity study.

Abstract
PURPOSE In pediatric, head trauma acute hydrocephalus is an uncommon but possible complication. Association with a subarachnoid hemorrhage is poorly described. METHODS We described a case of an 8-year-old girl with acute hydrocephalus secondary to peri-mesencephalic subarachnoid hemorrhage after mild head trauma resolved with external ventricular drainage. Furthermore, we have conducted a review of the literature about this complication in pediatric head trauma. DISCUSSION AND CONCLUSION Acute hydrocephalus related to post-traumatic peri-mesencephalic subarachnoid hemorrhage (tSAH) is an unknown entity in pediatric head trauma. According to our experience, traumatic peri-mesencephalic SAH should be under close clinical monitoring to identify post-traumatic hydrocephalus (PTH), a potentially fatal complication in pediatric mild head trauma.

Abstract
In allogeneic hematopoietic stem cell transplantation, donor αβ T cells attack recipient tissues, causing graft-versus-host disease (GVHD), a major cause of morbidity and mortality. A central question has been how GVHD is sustained despite T cell exhaustion from chronic antigen stimulation. The current model for GVHD holds that disease is maintained through the continued recruitment of alloreactive effectors from blood into affected tissues. Here, we show, using multiple approaches including parabiosis of mice with GVHD, that GVHD is instead primarily maintained locally within diseased tissues. By tracking 1,203 alloreactive T cell clones, we fitted a mathematical model predicting that within each tissue a small number of progenitor T cells maintain a larger effector pool. Consistent with this, we identified a tissue-resident TCF-1+ subpopulation that preferentially engrafted, expanded, and differentiated into effectors upon adoptive transfer. These results suggest that therapies targeting affected tissues and progenitor T cells within them would be effective.

Abstract
In response to infections and stress, hematopoiesis rapidly enhances blood and immune cell production. The stage within the hematopoietic hierarchy that accounts for this regeneration is unclear under natural conditions in vivo. We analyzed by differentiation tracing, using inducible Tie2- or Flt3-driven Cre recombinase, the roles of mouse hematopoietic stem cells (HSCs) and multipotent progenitors (MPPs). During polymicrobial sepsis, HSCs responded transcriptionally and increased their proliferation and cell death, yet HSC differentiation rates remained at steady-state levels. HSC differentiation was also independent from the ablation of various cellular compartments-bleeding, the antibody-mediated ablation of granulocytes or B lymphocytes, and genetic lymphocyte deficiency. By marked contrast, the fate mapping of MPPs in polymicrobial sepsis identified these cells as a major source for accelerated myeloid cell production. The regulation of blood and immune cell homeostasis by progenitors rather than stem cells may ensure a rapid response while preserving the integrity of the HSC population.

Abstract
BACKGROUND Papillary thyroid cancer (PTC) is the most frequent thyroid tumor. The tissue inhibitor of metalloproteinase-3 (TIMP3) gene encodes a matrix metalloproteinases inhibitor that exerts a tumor suppressor role in several tumor types. TIMP3 is frequently downregulated in PTC by promoter methylation. We have previously functionally demonstrated that TIMP3 exerts an oncosuppressor role in PTC: TIMP3 restoration in the PTC-derived NIM1 cell line affects in vitro migration, invasion and adhesive capability, while reduces tumor growth, angiogenesis and macrophage recruitment in vivo. To get a deeper insight on the mediators of TIMP3 oncosuppressor activity in thyroid tumors, here we focused on the TIMP3 related transcriptome. METHODS TCGA database was used for investigating the genes differentially expressed in PTC samples with low and high TIMP3 expression. Genome wide expression analysis of clones NIM1-T23 (expressing a high level of TIMP3 protein) and NIM1-EV (control empty vector) was performed. Gene sets and functional enrichment analysis with clusterProfiler were applied to identify the modulated biological processes and pathways. CIBERSORT was used to evaluate the distribution of different immunological cell types in TCGA-PTC tumor samples with different TIMP3 expression levels. Real time PCR was performed for the validation of selected genes. RESULTS Thyroid tumors with TIMP3-high expression showed a down-modulation of inflammation-related gene sets, along with a reduced protumoral hematopoietic cells fraction; an enrichment of cell adhesion functions was also identified. Similar results were obtained in the TIMP3-overexpessing NIM1 cells in vitro model, where a down-regulation of immune-related function gene sets, some of which also identified in tumor samples, was observed. Interestingly, through enrichment analysis, were also recognized terms related to cell adhesion, extracellular matrix organization, blood vessel maintenance and vascular process functions that have been found modulated in our previous in vitro and in vivo functional studies. CONCLUSIONS Our results highlight the correlation of TIMP3 expression levels with the regulation of inflammatory functions and the immune infiltration composition associated with different PTC prognosis, thus providing a broader view on the oncosuppressor role of TIMP3 in PTC.

Abstract
We report the case of a patient with metastatic renal cell carcinoma who developed Takotsubo syndrome (TTS) 6 days after starting pembrolizumab plus axitinib as first-line treatment. Coronary angiogram was negative for obstructive coronary artery disease and echocardiogram revealed a depressed left ventricular ejection fraction with apical akinesis. Axitinib was discontinued and myocardial contractile function fully recovered 23 days after the initial presentation. The treatment was safely resumed and granted a partial response of disease. A literature review regarding TTS in patients receiving VEGFR tyrosine kinase inhibitors and/or immune checkpoint inhibitors was performed. TTS is reported as a rare adverse event and the possible causal relationship between TTS and antineoplastic therapy is still unclear. Further research is warranted to better understand cardiotoxicity mechanisms and their management.

Abstract
BACKGROUND A more severe course of COVID-19 was associated with low levels of Vitamin D (VitD). Moreover in vitro data showed that VitD up-regulates the mRNA of the Angiotensin Converting Enzyme 2 (ACE-2), the SARS-COV-2 receptor in different type of cells. ACE-2 is expressed in several type of tissues including thyroid cells, on which its mRNA was shown to be up-regulated by interferon-gamma (IFN-γ). The aim of the present study was to investigate if treatment with VitD alone or in combination with IFN-γ would increase ACE-2 both at mRNA and protein levels in primary cultures of human thyrocytes. MATERIALS AND METHODS Primary thyroid cell cultures were treated with VitD and IFN-γ alone or in combination for 24 h. ACE-2 mRNA levels were measured by Real-time Polymerase Chain Reaction (RT-PCR). The presence of ACE-2 on thyroid cell membrane was assessed by immunocytochemistry basally and after the previous mentioned treatments. RESULTS ACE-2 mRNA levels increased after treatment with VitD and IFN-γ alone. The combination treatment (VitD + IFN-γ) showed an additive increase of ACE-2-mRNA. Immunocytochemistry experiments showed ACE-2 protein on thyroid cells membrane. ACE-2 expression increased after treatment with VitD and IFN-γ alone and further increased by the combination treatment with VitD + IFN-γ. CONCLUSIONS VitD would defend the body by SARS-COV2 both by regulating the host immune defense and by up-regulating of the expression of the ACE-2 receptor. The existence of a co-operation between VitD and IFN-γ demonstrated in other systems is supported also for ACE-2 up-regulation. These observations lead to an increased interest for the potential therapeutic benefits of VitD supplementation in COVID-19.

Abstract
Abstract
Background
In the ISCHEMIA trial, patients with chronic coronary syndromes (CCS) and moderate or severe ischemia had no significant difference in combined ischemic events with an initial invasive compared with a conservative strategy [1]. Coronary computed tomography angiography (CCTA) was part of the pre-randomization workup of ISCHEMIA and is gaining popularity over ischemia testing or initial invasive coronary angiography (ICA) as the initial diagnostic strategy for CCS [2].
Purpose
To analyse whether the results of the ISCHEMIA trial had a sizeable impact on the diagnostic algorithm for CCS by analysing trends in referral to ICA and/or revascularization.
Methods
ICAs performed in CCS patients between November 2019 and February 2022 at a high-volume centre were analysed. Two groups were defined based on procedure date: i) pre-ISCHEMIA, including ICAs performed before March 2020 (date of trial publication); ii) post-ISCHEMIA, including ICAs performed ≥3 months (i.e., blanking period) after trial publication. The primary outcome was the incidence of referral to ICA by CCTA. Secondary objectives included referral to ICA or revascularization by ischemia testing, referral to revascularization by CCTA, and referral by CCTA to ICA that did not require further intervention.
Results
A total of 2,365 patients qualified for the analysis, of which 487 (20.6%) and 1878 (79.4%) in the pre-ISCHEMIA and post-ISCHEMIA groups, respectively. There were no notable differences in baseline characteristics between groups. The primary outcome occurred more frequently in the post-ISCHEMIA group (73.5% vs 32.5%, p<0.01). Referral to ICA by ischemia testing was lower in the post-ISCHEMIA group (31.6%, vs 52.5% p<0.01), while referral for revascularization by CCTA was more frequent (8.3% vs 12.0% p<0.01). There were no significant differences in referral to revascularization by ischemia testing (3.4% vs 3.0%, p=0.73) and referral by CCTA to ICA that did not require further intervention (60.3% vs 60.8%, p=0.90).
Conclusions
At two years from publication, the ISCHEMIA trial seems to have impacted significantly on the decision-making algorithm for patients with CCS. The frequency of referral to ICA and revascularization by CCTA considerably increased, paralleled by decreased referral to ICA by ischemia testing.

Abstract
The Italian historic centers have an architectural and archeological heritage widespread in the urban structure, which is not always easily accessible due to the orography and materials the streets and the squares are paved with. The topic of the urban accessibility is extremely complex and not easy to solve, also because the removal and overcoming of the architectural and sensorial barriers that could alter the original layout and consolidated historical memory must be avoided. The research investigates the accessibility and usability conditions of the urban environment between the Langobardic building and archeological sites in Pavia (Italy) to identify pedestrian routes that can be covered by weak persons in autonomy or with the help of a companion. The analysis and synthesis of the urban environment produce some maps which report the level of accessibility of the streets and allow to identify the best route between the Langobardic masterpieces in the downtown. The adopted evaluation system is the result of an investigation methodology defined and consolidated over the years by the activities of a group of researchers from the University of Pavia and is independent of the heritage of Langobardic origin; the same methodology can also be used to other types of widespread heritage in the historic center of the city (Romanesque, Lombard Gothic, etc.). The same methodology can be exported to other historical centers and can constitute the tool for the promotion of the architectural and archaeological heritage.

Abstract
Hematopoietic stem cells (HSCs) produce highly diverse cell lineages. Here, we chart native lineage pathways emanating from HSCs and define their physiological regulation by computationally integrating experimental approaches for fate mapping, mitotic tracking, and single-cell RNA sequencing. We find that lineages begin to split when cells leave the tip HSC population, marked by high Sca-1 and CD201 expression. Downstream, HSCs either retain high Sca-1 expression and the ability to generate lymphocytes, or irreversibly reduce Sca-1 level and enter into erythro-myelopoiesis or thrombopoiesis. Thrombopoiesis is the sum of two pathways that make comparable contributions in steady state, a long route via multipotent progenitors and CD48hi megakaryocyte progenitors (MkPs), and a short route from HSCs to developmentally distinct CD48−/lo MkPs. Enhanced thrombopoietin signaling differentially accelerates the short pathway, enabling a rapid response to increasing demand. In sum, we provide a blueprint for mapping physiological differentiation fluxes from HSCs and decipher two functionally distinct pathways of native thrombopoiesis. Hematopoietic stem cells produce diverse cell lineages. Here, the authors apply single-cell RNA-seq, computational integration of non-perturbative approaches for fate-mapping, and mitotic tracking to chart lineage decisions in native hematopoiesis and identify megakaryocyte progenitors that directly link HSCs to megakaryocytes.

Abstract
We use resonant inelastic x-ray scattering to probe the propagation of plasmons in the electron-doped cuprate superconductor Sr_{0.9}La_{0.1}CuO_{2}. We detect a plasmon gap of ∼120 meV at the two-dimensional Brillouin zone center, indicating that low-energy plasmons in Sr_{0.9}La_{0.1}CuO_{2} are not strictly acoustic. The plasmon dispersion, including the gap, is accurately captured by layered t-J-V model calculations. A similar analysis performed on recent resonant inelastic x-ray scattering data from other cuprates suggests that the plasmon gap is generic and its size is related to the magnitude of the interlayer hopping t_{z}. Our work signifies the three dimensionality of the charge dynamics in layered cuprates and provides a new method to determine t_{z}.

Abstract
Abstract
Study question
Does Continuous Single Culture Medium NX, an embryo culture medium containing 1mM lactate, support increased blastocyst development over high lactate Vitrolife G1/G2 Series sequential culture?
Summary answer
There is a statistically significant increase in day 5 usable blastocysts in low lactate culture medium compared to the one with high lactate medium.
What is known already
Studies have shown that day 5 is the most desirable day to obtain blastocysts that are of an expansion, grade and quality to be utilized for transfer and/or vitrification procedures as those result in the highest success of clinical pregnancy,as compared to day 6/ 7 blastocysts, that do not meet criteria. Moreover, recent studies have indicated that there is an increase in chromosomal correctness of embryos cultured in a 1mM lactate environment as opposed to the higher 6-10mM lactate concentrations that have historically been believed necessary for successful blastocyst culture and resulting pregnancy.
Study design, size, duration
A prospective split sibling oocytes study was performed on 50 ICSI and IMSI cycles from October 2020 through April 2021. Oocytes were divided into the low lactate medium and high lactate gradient medium immediately following ICSI/IMSI and thereafter cultured in those medium until the final day of blastocyst culture. All patient ages were included in the sample population.
Participants/materials, setting, methods
This study was carried out in a private clinic. All patient stimulation protocol information and diagnosis’ were recorded; however, there was no restriction on participation. The endpoint was to analyse the resulting usable blastocyst rates on day 5 and day 6 in both arms of the study, using a denominator of normal 2PN fertilization. If a blastocyst was transferred or cryopreserved on day 5 or day 6, it was determined to be usable.
Main results and the role of chance
The resulting data was stratified not only by day 5 and day 6 usable blastocyst rates but also by patient age. It illustrates a statistically significant improvement in day 5 usable blastocysts for patients <35 in CSCM-NXC vs G1/G2 at 56% and 42%, respectively, a 14% increase (p < .05). The overall day 5 usable blastocyst rate was also statistically significant in CSCM-NXC (47%) as compared to G1/G2 (36%), (p < .05) with all ages considered. Additionally, on day 5, there was a higher percentage of usable blastocysts demonstrated in low lactate vs high in patients aged 35-37 (65% vs 42%, respectively) and 41-42 (41% vs 15%). Statistical significance was reversed in patients <35 on day 6, with G1/G2 having 24% usable blasts and CSCM-NXC 10% (p < .05). Interestingly, though not significant, G1/G2 had an increase in usable blastocyst percentage on day 5 in patients >42 (20% vs 11%), but overall, CSCM-NXC saw an increase in that same age group by 16%.
Limitations, reasons for caution
Though statistical significance was found in this study, a greater number will help to bolster the statistical power of the observations. Additionally, more studies are needed in order to ascertain if low lactate has an effect on the development prior to ICSI and resulting culture.
Wider implications of the findings
The mechanism of action that leads to the successful embryo development in low lactate embryo culture medium is vastly unknown, so further studies are required in order to understand the complexities and the impact of the observations provided.

Abstract
Abstract
Study question
Do kinetic parameters change among euploid, mosaic and aneuploid blastocysts? Is the KIDscoreTMDay5 version 3.0 (KS-5.3) correlated to preimplantation genetic testing for aneuploidies (PGT-A) results?
Summary answer
The KS-5.3 differs in embryo ploidy classes. The analysis of the kinetic variables showed that the aneuploid embryos were significantly slower than euploid and mosaic.
What is known already
Chromosomal abnormalities affect more than 50% of embryos in women with >35 years of age and PGT-A is the best way to predict embryo’s ploidy status decreasing implantation failure and miscarriage. However, this procedure is not always possible due to social or moral issues. So, the use of the non-invasive time lapse monitoring could be helpful to determine the morphokinetic characteristics in the different ploidy classes. KS-5.3 (vitrolife,Sweden) is a scoring model based on morphokinetic data, developed to predict the pregnancy rate of day-5 blastocysts. Recent publications showed differences in kinetic parameters between euploid and aneuploid embryos.
Study design, size, duration
This retrospective study analyzed 728 blastocysts with PGT-A results obtained at Villa Mafalda Clinic from May 2020 to June 2021. Embryos were cultured in EmbryoScope+ time-lapse system (Vitrolife) at 37 °C, 6%CO2, and 5% O2. The PGT-A was performed using next-generation sequence (NGS) technology on the trophectoderm biopsy sample on day 5/6/7. Automatic annotations for division times and quality gradings were performed by senior embryologists and all kinetic values were reported in hours post microinjection.
Participants/materials, setting, methods
728 blastocysts were classified in: (E) euploid (n = 172), (M) mosaicism (n = 171) and (A) aneuploid (n = 385). In this study, they were considered KS-5.3 and the following kinetic variables: the time to reach 2 cells (t2), 3 cells (t3), 4 cells (t4), 5 cells (t5), and the blastocyst formation (TB). Continuous variables were reported as the median and interquartile range (IQR). For the statistical analysis, nonparametric tests were performed and p < 0.05 was considered statistically significant.
Main results and the role of chance
KS5.3 was significantly different between groups [E = 6.6(4.6-7.9) vs M = 5.3(2.9-7.2) vs A = 4.0(2.5-6.6), p < 0.0001]. It was significantly higher in euploid than in mosaic and aneuploid (EvsM p = 0.0007, EvsA p <0.0001, MvsA p = 0.0077). A significant delay in t2,t3,t4 and tb was showed in aneuploid embryos compared to euploid and mosaic, whereas there was no significant difference between euploid and mosaic: [t2: E = 25.80 (24.56-28.09), M = 25.99 (24.49-28.91), A = 27.02 (25.30-29.47), EvsA p <0.0001, AvsM p = 0.03, EvsM p = 0.32]; [t3: E = 37.08 (34.74-39.34), M = 36.69 (34.55-40.02), E = 38.45 (35.93-41.14), EvsA p = 0.0003, MvsA p = 0.002, EvsM p >0.99]; [t4: E = 38.28 (35.63-41.19), M = 38.49 (35.47-42.13), A 39.72 (37.25-43.31), EvsA p = 0.0001, MvsA p = 0.02, EvsM p = 0.65]; [tb: E = 107.70 (102.20-114.30), M = 110.10 (103.60-116.80), A = 113.7 (106.80-122.70), EvsA p <0.0001, MvsA p <0.0001, EvsM p = 0.42]. As for t5, there were no differences among the groups. Longer cell cycles in aneuploid embryos could be associated with activated DNA repair mechanism or during chromosome segregation. Instead, regarding the mosaics, there was a significant difference with euploid embryos only in KS5.3. The age was similar between euploid and mosaic [E = 36.29 (33.42-39.00) vs M = 36.71 (34.00-39.33) p = 0.99], whereas that was significantly higher in aneuploid embryos [A = 39.11(36.01-42.27), EvsA/EvsM p <0.0001].
Limitations, reasons for caution
All these findings have to be validated in a larger sample size. Furthermore, for the retrospective nature of this study, there were some confounding factors, such as protocol of stimulation, female age, and malefactor. This research did not consider the importance of every single kinetic parameter.
Wider implications of the findings
A further study is needed to verify if there is a correlation between morphology and ploidy status. This could clarify the difference in KS-5.3 between euploid and mosaic. In order to decrease age bias, we should enlarge the sample size to analyze a subgroup of patients with higher maternal age.

Abstract
Study question
Which are the determining factors influencing the success rate of egg donation programs with imported vitrified oocytes?
Summary answer
Number of oocytes available after warming, male BMI and semen characteristics are critical parameters influencing reproductive results of oocyte donation programs with imported vitrified oocytes
What is known already
The use of vitrified oocytes from foreign banks and the performance of ICSI using fresh sperm from the recipient's partner is a widely used method of heterologous fertilisation. Recent evidence has questioned the overall effectiveness of this approach: vitrification and warming may reduce the number of oocytes available for insemination, resulting in a lower rate of live births per cycle. Recent studies have attempted to define the right clinical strategy to improve the effectiveness of oocyte vitrification cycles, stressing the importance of the number of imported oocytes (8-9 oocytes) and transfer to the blastocyst stage.
Study design, size, duration
Observational longitudinal cohort study of 431 cycles of oocyte donation conducted between January 2015 and February 2019. A total of 398 couples (mean female age: 43.2 ± 3.5, 28-50 years; mean male age: 44.7 ± 6.1, 28-73 years) underwent an IVF cycle with imported donated vitrified oocytes (mean donor age: 25.2 ± 3.5, 19-34 years). All consecutive oocyte donation cycles conducted at the centre for Reproductive Medicine of the European Hospital in Rome were included.
Participants/materials, setting, methods
In order to assess which factors are associated with the various outcomes, uni-and multi-variable analyses were conducted. In the multivariable analyses, variables that showed a p value<0.1 in the univariable analyses were included in the final model. The results were presented as Odds Ratio (OR). The corresponding 95% Confidence Interval (95% CI) was also exposed. A p value <0.05 was considered statistically significant. All analyses were performed with STATA v16.1 statistical software.
Main results and the role of chance
A univariate analysis was carried out showing that among the demographic characteristics studied, the only one that proved significantly able to influence the outcome of the pregnancy test was male BMI. In 49% of unsuccessful cycles, the male BMI was above 25 (p = 0.03). The correlation is confirmed when comparing cycle outcomes in couples with normal/underweight vs overweight/obese men (p = 0.03). The relationship between female or donor BMI and treatment outcome, however, was not statistically significant. The day on which embryo transfer is performed affects the outcome of the cycle: transferring on day 2 compared to day 5 reduces the probability of clinical pregnancy (ET in day 2= positive clinical pregnancy in 4/16 (25%); ET in day 3= 158/307 (51.4%); ET in day 5=40/67 (59.7%). The relationship between male BMI classes and sperm parameters was studied: the distribution of concentration is different in the 3 BMI groups (p = 0.011); in particular, obese men have a significantly lower concentration than normal-weight men (p = 0.006 after Bonferroni correction). There were no statistically significant differences in volume (P = 0.722), morphology (p = 0.100) and motility (p = 0.179), although there was a downward trend in motility, with a reduction in obese subjects compared to normal weight.
Limitations, reasons for caution
This is an observational study and our findings are in contrast with previous studies which do not show any correlation between male partner BMI categories and reproductive outcomes in egg donation programs.
Wider implications of the findings
Our study shows that the number of oocytes available after warming, male BMI, semen characteristics and blastocyst transfer are critical parameters able to influence the reproductive outcomes of egg donation programs with imported vitrified oocytes.

Abstract
OBJECTIVE Since the outbreak of COVID-19 pandemic, the international scientific community aimed at developing a vaccine to protect against the infection and prevent serious forms of the disease. To date, various adverse events of COVID-19 vaccines have been reported, mostly mild to moderate. MATERIALS AND METHODS In this short communication, we reviewed available literature and described the most frequent otolaryngology adverse events reported after COVID-19 vaccination. RESULTS The most frequent adverse events following COVID-19 vaccine described in the literature are represented by audiovestibular symptoms, such as tinnitus, sudden sensorineural hearing loss, vertigo, and dizziness. Other side effects include facial nerve palsy, epistaxis, and oral manifestations (lichen planus, bleeding, ulcers, and vesicles). CONCLUSIONS COVID-19 vaccine is of utmost importance in limiting the spread of SARS-CoV-2. Otolaryngology-related side effects have been described, but none was severe or life threatening. The mechanisms underlying these effects are still mostly unknown.

Abstract
Abstract Alcohol is a legal and yet detrimental psychoactive substance, capable of establishing addiction and impacting the physical, mental, social, and economic health of people. Alcohol intake causes a large variety of tissue damages severely impacting the nervous system, digestive and cardiovascular systems and causing oral cavity, oropharyngeal, hypopharyngeal, esophageal, colon-rectal, laryngeal, liver and intrahepatic bile duct, and breast cancers. Alcohol can also play a role in the pathogenesis of diabetes mellitus, cardiomyopathy and hemorrhagic strokes. When drunk during pregnancy it is proved to be responsible for serious damage to fetuses causing a wide range of pathological conditions from miscarriage to Fetal Alcoholic Spectrum Disorder (FASD). Acute ethanol intoxication happens when the amount of alcohol consumed is greater than the disposal capacity of the liver, causing an accumulation of its metabolites displayed by initial dysphoria and disinhibition. Nausea, vomiting, memory loss could happen. Although, it can lead to more serious conditions like impaired speaking, impaired coordination, unstable gait, nystagmus, stupor, or coma. Respiratory depression and death could also happen in such cases. Unfortunately, diagnosis of acute alcohol intoxication is difficult because most of the drinkers deny or minimize their assumption. It is dramatically important to assess when the last intake happened to avoid withdrawal syndrome. Alcohol acute intoxication can be considered a serious harm to health and a relevant issue for healthcare provid-ers working in emergency rooms. Differential diagnosis is crucial to avoid serious outcomes. There is no consensus about therapies for acute intoxication, but supportive and symptomatic treatments were proved effective. The repercussions of alcohol misuse over drinkers' social, familiar, economical and working life enhance the importance of a multidisciplinary approach in such cases.

Abstract
BACKGROUND Delirium is thought to be common across various settings of care; however, still little research has been conducted in rehabilitation. AIM We investigated the prevalence of delirium, its features and motor subtypes in older patients admitted to rehabilitation facilities during the three editions of the "Delirium Day project". METHODS We conducted a cross-sectional study in which 1237 older patients (age ≥ 65 years old) admitted to 50 Italian rehabilitation wards during the three editions of the "Delirium Day project" (2015 to 2017) were included. Delirium was evaluated through the 4AT and its motor subtype with the Delirium Motor Subtype Scale. RESULTS Delirium was detected in 226 patients (18%), and the most recurrent motor subtype was mixed (37%), followed by hypoactive (26%), hyperactive (21%) and non-motor one (16%). In a multivariate Poisson regression model with robust variance, factors associated with delirium were: disability in basic (PR 1.48, 95%CI: 1.17-1.9, p value 0.001) and instrumental activities of daily living (PR 1.58, 95%CI: 1.08-2.32, p value 0.018), dementia (PR 2.10, 95%CI: 1.62-2.73, p value < 0.0001), typical antipsychotics (PR 1.47, 95%CI: 1.10-1.95, p value 0.008), antidepressants other than selective serotonin reuptake inhibitors (PR 1.3, 95%CI: 1.02-1.66, p value 0.035), and physical restraints (PR 2.37, 95%CI: 1.68-3.36, p value < 0.0001). CONCLUSION This multicenter study reports that 2 out 10 patients admitted to rehabilitations had delirium on the index day. Mixed delirium was the most prevalent subtype. Delirium was associated with unmodifiable (dementia, disability) and modifiable (physical restraints, medications) factors. Identification of these factors should prompt specific interventions aimed to prevent or mitigate delirium.

Abstract
A Python-based analysis pipeline for the fast analysis of X-ray and neutron reflectivity data using neural networks is presented. The Python package mlreflect is demonstrated, which implements an optimized pipeline for the automated analysis of reflectometry data using machine learning. The package combines several training and data treatment techniques discussed in previous publications. The predictions made by the neural network are accurate and robust enough to serve as good starting parameters for an optional subsequent least-mean-squares (LMS) fit of the data. For a large data set of 242 reflectivity curves of various thin films on silicon substrates, the pipeline reliably finds an LMS minimum very close to a fit produced by a human researcher with the application of physical knowledge and carefully chosen boundary conditions. The differences between simulated and experimental data and their implications for the training and performance of neural networks are discussed. The experimental test set is used to determine the optimal noise level during training. The extremely fast prediction times of the neural network are leveraged to compensate for systematic errors by sampling slight variations in the data.

Abstract
Velopharyngeal dysfunction (VPD) diagnosis and speech surgery outcomes are currently based solely on subjective evaluation criteria consisting of perceptual speech assessment and functional imaging. This study describes an objective and comparable method in VPD assessment and investigates the concurrence between the objective and subjective evaluations. The present study included 20 paediatric patients presenting with VPD after primary repair (intravelar veloplasty) of cleft palate. Our protocol was based on computerized analysis of voice parameters by means of an objective tool, spectrography integrated with Multi-Dimensional Voice Program (MDVP). The protocol also included perceptual evaluation by speech therapist and phoniatrician (consensus listening), and parents. This is a single surgeon, single centre experience and all patients underwent a secondary Furlow's palatoplasty. Assessments were performed pre- and postoperatively and upon completion of speech therapy. Results were compared using the two-tailed t student test for paired data. Statistical significance was set for p-values <0.05. Data analysis confirmed an improvement in velopharyngeal closure after surgery and speech therapy consistently with the results of perceptual evaluations. The results of the study confirmed the availability and reliability of an objective method for VPD evaluation based on the analysis of voice parameters with investigations that are simple and easily available in a hospital setting.

Abstract
ABSTRACT COVID-19 has dramatically affected working forces. We aim to report our occupational medicine service's experience in managing suspected COVID-19 cases during the pandemic through a retrospec-tive observational study. We compared the number of days employees were absent from work due to flu-like symptoms from March 2020 to February 2021 to the same period the previous year (2019-2020). Two hundred thirty-four patients (+47.2% compared to the previous year) who tested negative for SARS-CoV-2 reported flu-like symp-toms; the number of days of absence from work was 2812 (+190.2% compared to the previous year). On average, employees with flu-like symptoms lost 12.07 working days compared to 6.12 in the previous year (p<0.0001). In conclusion, in our sample COVID-19 has increased the number of working day loss. However, our approach proved to be important, especially during the first months of the pandemic, to limit SARS-CoV-2 spread in workplaces.

Abstract
Introduction Delirium and sarcopenia are common, although underdiagnosed, geriatric
syndromes. Several pathological mechanisms can link delirium and low skeletal muscle mass, but few studies have investigated their association. We aimed to investigate (1) the association between delirium and low skeletal muscle mass and (2) the possible role of calf circumference mass in finding cases with delirium. Methods The analyses were conducted employing the cross-sectional “Delirium Day” initiative, on patient 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes and hospices in Italy in 2017. Delirium was diagnosed as a 4 + score at the 4-AT scale. Low skeletal muscle mass was operationally defined as calf circumference ≤ 34 cm in males and ≤ 33 cm in females. Logistic regression models were used to investigate the association between low skeletal muscle mass and delirium. The discriminative ability of calf circumference was evaluated using non-parametric ROC analyses. Results A sample of 1675 patients was analyzed. In total, 73.6% of participants had low skeletal muscle mass and 24.1% exhibited delirium. Low skeletal muscle mass and delirium showed an independent association (OR: 1.50; 95% CI 1.09–2.08). In the subsample of patients without a diagnosis of dementia, the inclusion of calf circumference in a model based on age and sex significantly improved its discriminative accuracy [area under the curve (AUC) 0.69 vs 0.57, p < 0.001]. Discussion and conclusion Low muscle mass is independently associated with delirium. In patients without a previous diagnosis of dementia, calf circumference may help to better identify those who develop delirium.

Abstract
OBJECTIVE Alterations of the olfactory function in patients affected by COVID-19 often have an early onset and a variable duration ranging from a few weeks to months. The aim of this study was to evaluate olfactory dysfunction persistence after recovery from COVID-19, and potential related clinical-demographic conditions. PATIENTS AND METHODS A total of 76 patients recovered from COVID-19 from at least 20 days with olfactory dysfunction during the infection were included in the study. For the subjective evaluation of olfactory function, a visual analogic scale (VAS) was used. The objective evaluation was performed with the use of the Sniffin' Sticks test. RESULTS Objective assessment of olfactory function revealed that 48 (63.16%) patients were found to be normosmic (TDI ≥ 30.5), 26 (34.21%) were hyposmic (TDI from 30.5 to 16.5) and two (2.63%) were anosmic (TDI ≤ 16.5) at the time of the evaluation. These results did not show a significant difference between subjective and objective tests (p = 0.45). Most patients recovered their sense of smell within the first two months after recovery while a portion (22.2%) still experienced olfactory alterations 4-6 months after SARS-CoV-2 infection. Patients who had not recovered their sense of smell had a significantly longer period of SARS-CoV-2 positivity compared to patients that fully recovered (36.07 ± 7.78 days vs. 29 ± 7.89 days; p = 0.04). CONCLUSIONS Our results suggest that the duration of the infection negatively correlates with the recovery of olfactory function.

Abstract
OBJECTIVE The COVID-19 pandemic has severely affected otolaryngology and head and neck activities, also involving diagnosis and treatment of patients with oncology diseases with consequent delays and tumor upstaging. The aim of this study was to describe the experience of our otolaryngology unit during the pandemic on patients with cancer of the head and neck, comparing data on anatomical site of origin and preferred treatment with pre-pandemic data. PATIENTS AND METHODS This study retrospectively analyzed the clinical records of patients treated for oncology disorders of the head and neck in the Otolaryngology Unit of the Policlinico Umberto I, Sapienza University of Rome, between March 10, 2020, and March 9, 2021. Data were compared with the same period of the previous year (March 10, 2019 - March 9, 2020). RESULTS During the pandemic, we treated 92 patients with malignant tumor of the head and neck, compared to 101 patients treated during the same period of 2019 (-8.91%). The most common anatomical sites of origin of the neoplasms were larynx, oral cavity, and oropharynx. Surgical approach was preferred in 57 patients (61.95%); non-surgical treatments were performed in 35 cases (38.05%). Compared to the same period of the previous year, we found a 12.90% decrease in the number of oncology patients undergoing surgery, while patients treated exclusively with non-surgical approaches increased by 18.42%. CONCLUSIONS Despite the impact of COVID-19 on the activity of our otolaryngology unit and on the whole healthcare system, diagnostic and therapeutic procedures for patients affected by malignancy of head and neck region were only minimally impacted.

Abstract
Abstract
Neutron and x-ray reflectometry (NR and XRR) are powerful techniques to investigate the structural, morphological and even magnetic properties of solid and liquid thin films. While neutrons and x-rays behave similarly in many ways and can be described by the same general theory, they fundamentally differ in certain specific aspects. These aspects can be exploited to investigate different properties of a system, depending on which particular questions need to be answered. Having demonstrated the general applicability of neural networks to analyze XRR and NR data before (Greco et al 2019 J. Appl. Cryst.
52 1342), this study discusses challenges arising from certain pathological cases as well as performance issues and perspectives. These cases include a low signal-to-noise ratio, a high background signal (e.g. from incoherent scattering), as well as a potential lack of a total reflection edge (TRE). By dynamically modifying the training data after every mini batch, a fully-connected neural network was trained to determine thin film parameters from reflectivity curves. We show that noise and background intensity pose no significant problem as long as they do not affect the TRE. However, for curves without strong features the prediction accuracy is diminished. Furthermore, we compare the prediction accuracy for different scattering length density combinations. The results are demonstrated using simulated data of a single-layer system while also discussing challenges for multi-component systems.

Abstract
Detecting depression on its early stages helps preventing the onset of severe depressive episodes. In this study, we propose an automatic classification pipeline to detect subclinical depression (i.e., dysphoria) through the electroencephalography (EEG) signal. To this aim, we recorded the EEG signals in resting condition from 26 female participants with dysphoria and 38 female controls. The EEG signals were processed to extract several spectral and functional connectivity features to feed a nonlinear Support Vector Machine (SVM) classifier embedded with a Recursive Feature Elimination (RFE) algorithm. Our recognition pipeline obtained a maximum classification accuracy of 83.91% in recognizing dysphoria patients with a combination of connectivity and spectral measures. Moreover, an accuracy of 76.11% was achieved with only the 4 most informative functional connections, suggesting a central role of cortical connectivity in the theta band for early depression recognition. The present study can facilitate the diagnosis of subclinical conditions of depression and may provide reliable indicators of depression for the clinical community.

Abstract
Abstract
Background
Patients undergoing percutaneous coronary intervention (PCI) are at risk of developing bleeding and/or thrombotic complications. Bleeding and thrombotic risk characteristics may overlap in some patients, which makes decision-making for dual antiplatelet therapy duration a clinical challenge. The actual proportion of PCI patients who have an increased bleeding risk and/or an increased thrombotic risk is unclear.
Purpose
Aim of this study is to identify sizeable and actionable proportions of patients at high bleeding risk (HBR) and/or at high thrombotic risk (HTR) in a contemporary cohort of PCI patients.
Methods
We retrospectively included all patients undergoing PCI at our Institution from November 2019 to April 2020 and identified those at HBR or HTR based on criteria from the Academic Research Consortium for High Bleeding Risk (ARC-HBR) or criteria from Giustino and colleagues, respectively. Since belonging to the HBR and HTR groups was non-mutually exclusive, patients were further stratified into 4 mutually exclusive subgroups: 1) HBR/HTR; 2) HBR, non-HTR; 3) non-HBR, HTR; and 4) non-HBR, non-HTR. In addition, the new ARC-HBR trade-off model (integrating patients' characteristics to define the individual risks of bleeding and thrombotic events) was applied to rank patients based on their computed risk scores for bleeding and thrombosis. Patients were categorized based on the ratio between the ARC-HBR thrombotic and the bleeding risk scores (i.e., high [1.5], intermediate [0.75–1.5], low [<0.75]).
Results
A total of 312 patients were included, of which 93 (30%) presented with HBR and 116 (37%) with HTR. Among patients with HBR, 41% presented with HTR. Among patients with HTR, 33% presented with HBR. Overall, 12.2% of patients had HBR/HTR, 17.6% had HBR, non-HTR, 25.0% had non-HBR, HTR, and 45.2% had non-HBR, non-HTR. Based on the ARC-HBR trade off score, 16.3% of patients had a higher risk of thrombosis than the risk of bleeding, 45.9% had similar risks, and 37.8% had a higher risk of bleeding than the risk of thrombosis. Among patients who had HBR/HTR, the trade-off model identified 8% as having a higher risk of thrombosis than the risk of bleeding and 18.4% as having a higher risk of bleeding than the risk of thrombosis.
Conclusions
Characterizing the risk of bleeding and thrombotic complications is an important prerequisite for tailoring strategies to individual patients, hence minimizing the risks and improving the outcome of PCI. More than half of patients undergoing PCI presented with HBR, HTR, or both. About 40% of patients presented with characteristics of high risk, which make them actionable (e.g., by using shorter durations of dual antiplatelet therapy in patients at HBR and non-HTR or using longer durations in patients at non-HBR and HTR). The ARC-HBR trade off model score is an additional useful tool that may be used to identify an additional quarter of actionable patients in the HBR/HTR category.

Abstract
Abstract
Background
There is growing interest in the possibility of using X-rays and hadrons (protons and carbon ions) for antiarrhythmic purposes both at the ventricular and the atrial level, but knowledge about the effects on cardiac tissue outside the target is still limited. Hadron therapy has the dosimetric advantage over photons of a greater ability to concentrate high doses on the target while minimizing the off-target dose. Oncological studies have shown a linear relationship between the mean total heart dose (Dm-heart) of X-rays and the long-term risk of heart damage, particularly when the Dm-heart is>5 Gray (Gy).
Objectives
We designed a prospective study aimed at investigating the effect of heavy particles on cardiac structure and function and on cardiac rhythm in patients undergoing hadrontherapy for intra or para-cardiac tumors.
Methods
Patients candidates to hadrontherapy with a mean predicted cardiac dose grather than zero underwent close cardiological monitoring including blood pressure detection, 12-lead ECG, 12-lead Holter ECG (including time-domain indices of heart rate variability in all cases and Brugada leads in selected cases), cardiac US and cardiac (troponin and natriuretic peptides) and inflammatory biomarkers. These assessments were obtained at baseline, during (ECG and biomarkers only) and at the end of the hadrontherapy cycle, and then every 3–6 months as appropriate. Physicists and radiotherapists collaborated to implement a robust optimization of the treatment plan aimed at minimizing cardiac dose. We present the results of the monitoring up to the end of the hadrontherapy.
Results
17 consecutive patients (56±18 years, range 20–77 years, 59% male) have been enrolled to date, including 3 cases (18%) of intra-cardiac tumors (2 primary and 1 metastatic), who have undergone to 16±6 sessions of radiotherapy each, in 71% of cases with respiratory gating during delivery. Most patients (76%) were treated with carbon ions, the remaining with protons (mean total dose on the neoplastic target 51.8±10.7 Gy, from 2 to 4.2 Gy per fraction). Sixty-one percent of patients had ≥1 cardiovascular risk factor, 6% had a known heart disease (valvular cardiomyopathy despite aortic valve replacement with biological prosthesis and post-surgical pericarditis). The mean dose on the whole heart was 3.58±2.05 Gy, the maximum dose was 33.78±23.99 Gy, with a very variable dose distribution on cardiac substructures depending on the tumor site (table). At the end of the scheduled radiotherapy sessions (24±9 days), no significant changes were observed in cardiac function, cardiac rhythm, ventricular repolarization, biomarkers and autonomic indices.
Conclusions
Hadrontherapy with protons and carbon ions aimed at the treatment of para-cardiac or intra-cardiac tumors allowed to maintain a low heart Dm and showed no signs of acute cardiac toxicity. The collection of potential cardiac effects in the medium and long term is ongoing.

Abstract
Abstract
Background
Mutations in the LMNA gene are associated with a high arrhythmic risk. The history of the disease in patients undergoing ICD implantation is poorly characterized.
Purpose
To evaluate the phenotype of patients with cardiolaminopathy at the time of first ICD implantation, the incidence, characteristics and timing of ventricular arrhythmias (VAs) during follow up and the predictive value of the European score (that assigns a point each to non-sustained VT (NSVT), left ventricular ejection fraction (LVEF)<45% at first contact, male sex and non-missense mutations) and of the Wahbi score (that also includes conduction disturbances) for both VAs and heart failure (HF) related outcomes.
Methods
Patients were identified retrospectively. Clinical and device data were collected at baseline and during follow-up.

We identified 26 patients (54% male, 42±8 years, 31% with familial history of sudden cardiac death, 31% with non-missense mutation) undergoing ICD implantation, 96% in primary prevention, 47% with single chamber ICD, 38% with dual chamber ICD. At the time of implantation, 30% had skeletal muscle involvement, 15% history of syncope, 4% of cardiac arrest, 62% previous NSVT. Also, 38% had a history of supraventricular arrhythmias and 61% had AV conduction disturbances. LVEF was 41±11%, 35% were in NYHA class ≥2, the mean European and Wahbi scores were 2.1±0.8 and 18.2±8.9, respectively. During 8.3±5 years, 15% were transplanted, 8% died due to HF, 4% underwent LVAD implantation, despite 31% having received an upgrade to CRT-D. Appropriate device interventions occurred in 46% of patients with a median time to first event of 29 months (IQR 13–93), for a total of 137 ATP, 51% of which effective (median 3ATP/patient, IQR 1–8) and of 26 shocks, 96% of which effective (median 2 shocks/patient, IQR 1–3); 12% had an arrhythmic storm. The first treated arrhythmia was a polymorphic VT/VF in 17%, a monomorphic VT in the others (medium cycle length 293±37 msec). Survival free from appropriate ICD interventions at 1 and at 5 years was 75% and 19% respectively in case of a European score ≥3 vs 94% and 82% in case of a score <3 (Logrank test p<0.01), 72% and 46% in case of Wahbi score ≥30 vs 100% and 86% with score <30 (p<0.01), with no differences in terms of death/transplant (figure). At last follow-up, 92% of patients a were taking beta-blocker, 42% amiodarone, 8% sotalol, 4% flecainide, 8% mexiletine. Also, 4% had undergone invasive VT ablation, 8% bilateral cardiac sympathetic denervation.
Conclusions
Patients with cardiolaminopathy are at a high risk of both arrhythmic and heart failure progression over the first decade after implantation of the first ICD. A European score ≥3 identifies patients with 5-year shock/ATP free survival of less than 20% but does not predict death/transplantation. The first arrhythmic event in these patients is more frequently a rapid monomorphic VT with modest ATP efficacy.

Abstract
OBJECTIVE Thyroidectomy is the primary cause of unilateral vocal fold paralysis (UVFP). A delay in rehabilitation may cause dysfunctional phenomena and worsen dysphonia. The main aim is to investigate the impact of early Speech Therapy (ST) on voice recovery in UVFP post-thyroidectomy and propose an appropriate treatment schedule. PATIENTS AND METHODS 93 patients with UVFP were analysed. 72 presented transient paralysis and 21 permanent ones. Individuals with permanent paralysis were retrospectively divided in two groups. Group A was composed of 11 patients (8 F, 3 M; mean age: 50.5 ± 8.6) who received ST within 8 weeks; Group B comprised 10 patients (7 F, 3 M; mean age: 57 ± 11.5) treated after more than 8 weeks. Videolaryngostroboscopy (VLS) was assessed and both objective and subjective voice parameters were collected. The non-parametric Wilcoxon test was applied to the sample. RESULTS The resolution of supraglottic compensations was observed in 91% of cases in Group A, whereas in only 40% of cases in Group B. A functional glottal closure occurred in 73% of patients in group A, while it was completely absent in group B. Group A showed a statistically significant difference between the values of Jitter, NHR, TMF and VHI collected pre-ST compared to that collected after 1 year. Conversely, a statistically significant difference was found only for VHI values in group B. CONCLUSIONS Early ST brings benefits to patients with permanent UVFP, both on voice recovery and on quality of life. A ST protocol should be applied both before and after thyroidectomy. The ST treatment should start early after surgery.

Abstract
Post-COVID-19 syndrome was defined as a persistent and protracted illness, which follows acute COVID-19 infection. This condition continues for more than 12 weeks and cannot be attributed to other clinical situations. Researchers and clinicians are allied in unraveling the molecular pathogenetic mechanisms and the clinical development of this unexpected SARS-CoV-2 infectious evolution. Anosmia, dysgeusia, fatigue, dyspnea, and 'brain fog' are common symptoms observed in the Post-COVID-19 syndrome, depicting a multiorgan involvement associated with injuries involving mainly cardiovascular, pulmonary, musculoskeletal, and neuropsychiatric systems. This commentary analyzes the state of the art of Post-COVID-19 interdisciplinary studies, confirming that we are facing a truly intricate biomedicine story.

Abstract
The protection of artistic and cultural heritage is a major challenge due to its peculiarities and its exposure to significant natural hazards. Several methodologies exist to assess the condition of artistic heritage and to protect it from exceptional actions. Moreover, novel digital technologies offer many solutions able to deliver a digital replica of artifacts of interest, so that a reduction in the uncertainties in the analysis models can be achieved. A rational approach to the preservation and protection of artistic heritage is based on traditional approaches supported and integrated by novel technologies, so that qualitative and quantitative indicators of the current condition of artistic heritage can be defined and validated in an interdisciplinary framework. The present paper reports the results of an approach to the maintenance and preservation of art objects housed in a museum complex based on a comprehensive digital path towards a Historical Digital Twin (HDT). A workflow aimed at estimating the stress regime and the dynamic properties of two sculptures, based on the detailed three-dimensional model resulting from a laser scanner survey, is illustrated and discussed. The results highlight the great advantages resulting from the integration of traditional and novel procedures in the field of conservation of artistic assets.

Abstract
Abstract
Study question
Could advanced paternal age influences the embryos aneuploidy rate in eggs donation cycles with poor sperm quality?
Summary answer
In case of severe male factors increased paternal age can affect embryos aneuploidy rate in egg donation cycles.
What is known already
While the impact of advanced maternal age on reproductive is well understood, the effect of paternal age on reproductive function is controversial. Many studies have shown that Advanced Paternal Age (APA) could impact on male fertility potential affecting testicular function and sperm quality. Moreover, APA also has been associated with increased epigenetics changes and DNA mutations. Increased paternal age could be associated with different types of disorders such as autism, schizopherenia and bipolar disorders. Egg donation cycles, controlling female variables, represent the ideal model for the study of the impact of paternal age on reproductive outcomes.
Study design, size, duration
We retrospectively analyzed 43 egg donation cycles (October 2014-January 2020) with ≥ 50% survival rate of vitrified/warmed oocyte. Only cycles with poor sperm quality were considered. Cycles were divided in two GROUPS: group–1 included male paternal age ≤ 45 while group–2 included male paternal age >45. Data, shown as avarage±SD, were analyzed with Chi square or Student-t test.
Participants/materials, setting, methods
Group–1 included 20 cycles and 219 oocytes, male age was 40,89 ±6.12; Group–2 included 17 cycles and 173 oocytes, male age was 51±6.06. Respectively, in Group 1 and in Group 2, donor age were 22.4±2.65 and 24.8±3.88 (NS). All oocytes were injected with abnormal sperm samples according to WHO 2010. Embryos were cultured in time-lapse system until blastocyst stage. Trophectoderm biopsy and PGT-A analysis were performed according to standardized laboratory protocols.
Main results and the role of chance
Oocytes survival rates in Group1 and 2 were 86% (188/219) and 90.7% (157/173) (NS), respectively. Fertilization rates in Group1 and –2 were 71.42 (135/189) and 73.45% (119/162) (NS), respectively. The total number of obtained embryos (transferred + frozen) were 81 and 801 in Group–1 and –2, respectively. The rates of obtained embryos per reiceved occytes were 37% (81/219) and 46.24% (80/173) in Group–1 and –2 (p < 0.7), respectively. The PGT-A analysis showed 38.7% (31/80) and 31.17% (24/77) of euploid (NS) and 25% (20/80)and 42.85% (33/77) of aneuploid embryos (P < 0.05) in Group–1 and –2, respectively. Mosaic embryos were 33.5% (26/80) and 27.27%(21/77), in Group–1 and –2, respectively. (NS). These results indicate that in presence of severe male factor, advanced paternal age could increase embryos aneuploidy rate raising incidence of chromosomal abnormalities.
Limitations, reasons for caution
Each donor was stimulated with different protocols according to her history and hormones levels. Nothing is known about which type of sperm parameters (semen amount, morphology or motility) have a major impact when focusing on the embryos genetic outcome.
Wider implications of the findings: To better known the effect of APA, it could be necessary identify embryos chromosomal abnormalities and the correlation with specific sperm parameters. Further studies should be done to confirm the APA effect in patients with severe male factors and define a cut-off male age where PGT-A should be recommended.

Abstract
Abstract
Study question
Can MACS increase euploid blastocyst rate in Pre-implantation Genetic Testing (PGT) cycles for AMA-APA (Advanced Maternal-Paternal Age) in patients with high sperm DNA fragmentation (SDF)?
Summary answer
A slight increase in euploid blastocyst rate was found using MACS in infertile patients with high SDF undergoing PGT cycles compared to the control group.
What is known already
Many authors have shown a close correlation between the presence of apoptotic markers on spermatozoa and the failure of assisted reproduction treatments. In normal physiological conditions, apoptotic spermatozoa with phosphatidylserine (PS) residues externalized on the plasma membrane, are eliminated along female genital tract, preventing oocyte fertilization. MACS eliminates apoptotic sperm whit PS residues using superparamagnetic microbeads conjugated with annexin V. This technique reduces the proportion of sperm with high rates of SDF and can be used to maximize ART procedures results. MACS application improves sperm quality, fertilization, cleavage and pregnancy rates reducing miscarriage rate.
Study design, size, duration
From June to November 2020, 10 couples in which MACS was applied to select non-apoptotic spermatozoa, were randomly enrolled in our study (MACS group) and 8 couples without MACS were considered as controls (No-MACS Group). All couples in both groups underwent a PGT cycle and had high sperm DNA Fragmentation (> 20%). A higher rate of euploid and diploid-euploid mosaic blastocysts were obtained in the MACS group compared to the control group.
Participants/materials, setting, methods
Patients with severe oligoastenoteratozoospermia were excluded. MACS protocol was performed as follows: semen sample was analyzed (WHO 2010) and washed with buffered medium; pellet was removed and a swim-up was performed. Retrieved spermatozoa were washed with a binding buffer (Miltenyi Biotec), centrifuged (400 g x 4 minutes) and supernatant discarded. Pellet was covered with Annexin-V and re-suspended. After 15 minutes incubation at room temperature, the sample was eluted through the column and collected for ICSI.
Main results and the role of chance
In MACS group, female and male mean age ± SD were 41.6 ± 2.1 and 43.5 ± 7.3, respectively. Female and male mean age ± SD were 41.7 ± 2.8 and 44.6 ± 8.1 in the No-MACS group, respectively. In MACS and No-MACS groups, injected oocytes were 44 and 35, fertilized oocytes were 32 (72.3%) and 27 (77.1%) (NS), blastocyst formation rates were 71.8% (23/32) and 48.1% (13/27) (NS), respectively. In No-MACS group, only 1 euploid and 1 diploid-euploid mosaic blastocysts were obtained (1/13 = 8%) (NS). In MACS group, 4 euploid blastocysts were formed (4/23 = 17.4%) whereas mosaic diploid-euploid blastocysts were 3/23 (13.0%) (NS). Aneuploid blastocysts were 16/23 (69.6%) in MACS group and 11/13 (84.6%) in No-MACS group (NS).
Limitations, reasons for caution
AMA and APA of couples enrolled should be considered as a limit of the study. A larger number of patients and biopsied blastocysts are needed to analyze clinical results and perform a robust statistical analysis establishing if MACS is useful to improve transferable blastocyst rate in patients with high SDF.
Wider implications of the findings: MACS is useful to select non apoptotic sperms; although fertilization, cleavage and blastocyst rates are not improved, aneuploid blastocysts rate slightly decreases using MACS. It I possible that, selecting spermatozoa free from PS residues, MACS allows to choose spermatozoa with a better DNA packaging, thus affecting the embryo ploidy.
